Study Arms (2)

Otitis associated with Bronchiolitis

EXPERIMENTAL

Only for city physicians: 800 children presenting with acute otitis media associated with bronchiolitis will undergo a rapid antigen diagnostic test for respiratory syncytial virus (RSV), influenza viruses, and SARS-CoV-2, using a nasopharyngeal swab.

Diagnostic Test: nasopharyngeal samples

Otitis not associated with Bronchiolitis

EXPERIMENTAL

Only for city physicians: A total of 1,100 children presenting with acute otitis media, without concomitant bronchiolitis, will undergo a rapid antigen diagnostic test for respiratory syncytial virus (RSV), influenza viruses, and SARS-CoV-2, using a nasopharyngeal swab.

Diagnostic Test: nasopharyngeal samples

Interventions

Intervention Model
SINGLE GROUP
Model Details: A nasopharyngeal specimen will be obtained from the eligible child. The procedure consists of inserting and gently rotating a swab into the posterior nasopharynx to perform a rapid antigen test (nasopharyngeal or nasal). The test provides results within 10 to 15 minutes and determines the presence or absence of respiratory syncytial virus (RSV), influenza viruses, and SARS-CoV-2.
